| plasminogen inactivators | <chemical> Important modulators of the activity of plasminogen activator. Four inhibitors, all belonging to the serpin family of proteins, have been implicated in plasminogen activation inhibition. They are pai-1, pai-2, protease-nexin, and protein c inhibitor (pai-3). All inhibit both the tissue-type and urokinase-type plasminogen activator. Pharmacological action: serine proteinase inhibitors. (12 Dec 1998) |
